Bucket Strategy
A way of organising a retirement portfolio into separate pots by time horizon — cash for near-term spending, bonds for the medium term, growth assets for the long term — so a market downturn doesn't force you to sell shares at a loss to pay this month's bills.
The problem it solves
Selling shares to fund living costs works fine when markets are rising. It's much worse when they've just fallen — you lock in a loss to pay for groceries, and if that happens early in retirement it can permanently dent how long your portfolio lasts (see sequence-of-returns risk). The bucket strategy separates "money I need soon" from "money that needs time to grow" so a downturn in the growth bucket never forces a sale there. Near-term spending draws from cash and short bonds instead, giving equities time to recover before you're forced to touch them.
How the buckets typically work
A common three-bucket setup holds bucket one (roughly one to three years of planned spending) in cash or a cash-equivalent, bucket two (several more years) in bonds or other lower-volatility assets, and bucket three (the remainder) in equities and other growth assets. You spend down bucket one first. Periodically — on a fixed schedule, or opportunistically when markets are up — you refill bucket one from bucket two, and top up bucket two from bucket three. The buckets aren't a fixed allocation you set once; they're a spending and rebalancing discipline layered on top of whatever allocation you hold.
What it doesn't do
A bucket strategy doesn't change your underlying expected return or make a given pot size last meaningfully longer than an equivalent single-portfolio approach with the same overall mix — the total risk you're carrying is largely the same either way. Its real value is psychological and procedural: it makes the "don't sell equities in a crash" rule concrete and easy to follow, and it can reduce the temptation to panic-sell everything when markets fall. It also adds complexity — more accounts or sub-portfolios to track, and judgement calls about exactly when to refill — that a single blended portfolio avoids.
Across borders
Bucket contents rarely sit in one place once you retire abroad. Your "cash bucket" might be a UK bank account, your "bond bucket" a euro-denominated fund, and your "growth bucket" a US brokerage — each with its own currency, and currency movement can dent a cash buffer just as easily as a stock-market fall can. Refilling buckets from overseas accounts can also trigger tax or reporting events in either country, so the timing you'd choose on pure spending logic may need to bend around a tax year-end. And if you move countries partway through retirement, "one to three years of spending" changes value the moment your home currency changes.
Common questions
How big should each bucket be?
There's no universally correct split — common patterns hold one to three years of spending in cash, a further several years in bonds or short-duration assets, and the remainder in growth assets, but the right sizes depend on your spending flexibility, other income (pensions, rental income) and how much sequence-of-returns risk you're willing to carry. Treat any specific ratio you read as a starting point to adjust, not a rule.
Isn't this just asset allocation with extra steps?
Mechanically, a bucket portfolio and a single blended portfolio with the same overall cash/bond/equity split can end up holding near-identical assets. The difference is behavioural and procedural: buckets give you an explicit refill rule (spend the cash bucket down, top it up from bonds or growth assets on a schedule or when markets allow) rather than a single number you adjust ad hoc. Some retirees find that structure easier to stick to under pressure than the equivalent blended portfolio, even though the maths can be similar.
Does Ember model bucket strategy directly?
No. Ember tracks your holdings by asset class (cash, bonds, equities and more) and projects your portfolio forward, but it doesn't currently implement bucket refill logic as a named feature. You can still use Ember to check whether your intended cash and bond buffers are large enough to cover a multi-year downturn without selling growth assets — that's a modelling question the underlying projections can help answer.
